Unknown Number Handling — Turn Every Unrecognized Caller into a CRM Opportunity
When a call or SMS arrives from a number not in your Bitrix24 CRM, SIMtrix detects it instantly and creates a new Lead automatically. Configurable per channel — no missed opportunities, ever.
Intelligent Detection for Every Unknown Interaction
SIMtrix matches every incoming number against your entire CRM in real time — and takes action when no match is found.
Real-Time CRM Number Matching
Every incoming call and SMS is matched against all contacts, leads, and deals in Bitrix24 within milliseconds. SIMtrix queries the CRM via REST API and checks phone number fields across all entity types. When no match is found, the number is flagged as unknown and the configured action is triggered — whether that is creating a Lead, logging an activity, or both.
Configurable Per Channel — Calls, SMS, or Both
You control exactly which channels trigger unknown number handling. Enable it for incoming calls only, incoming SMS only, or both. This flexibility lets you tailor the behavior to your business — for example, auto-create Leads from calls but only log SMS from unknown senders, or vice versa. Configuration is done from the SIMtrix admin panel with a single toggle per channel.
Pipeline and Agent Assignment
When a new Lead is created from an unknown number, it is placed in the pipeline and stage you specify. The responsible agent is determined by the SIM card mapping — the user assigned to the SIM that received the call or SMS becomes the Lead owner. This ensures every new Lead lands in the right hands immediately, with no manual routing required.
How It Works
From unknown number to CRM Lead — fully automatic, fully configurable.
Incoming Call or SMS Arrives
Your Android phone receives a call or SMS from a number that is not saved in your phone contacts or CRM.
SIMtrix Searches Bitrix24
The number is sent to the SIMtrix server, which queries Bitrix24 contacts, leads, and deals. The lookup completes in 200-500ms.
No Match Found — Action Triggered
When no CRM match exists, SIMtrix applies your configured rules: create a new Lead, log the interaction as an activity, or both.
Lead Created with Full Context
A new Lead is created in Bitrix24 with the phone number, interaction type (call or SMS), timestamp, and the responsible agent pre-assigned based on SIM card mapping.
Who Is This For?
Unknown number handling ensures no potential customer slips through the cracks — for any team.
Sales Teams
Every missed call or cold inbound from an unknown number becomes a Lead in your pipeline automatically. No more sticky notes, no more forgotten callbacks. Your sales pipeline captures 100% of inbound interest.
Marketing Teams
Running campaigns with a phone number as the CTA? Every response from an unknown number creates a Lead with the interaction details — giving you precise attribution and zero data loss.
Service Businesses
New customers often call or text before they are in your CRM. With unknown number handling, their first interaction creates a Lead — so by the time you call back, you already have a CRM record with context.
